need an option for ignore directories

[leemason]

I'm using this in conjunction with a translation module, and the documenter is picking up the php files from that library, which isn't great.

tried to add an option for ignore, but it doesn't work.

Hi and thanks for this feedback, this feature will be placed in the 0.5.0 release and is related to the PR #10.

I'll try to have a moment to merge this pull request and implement unit tests for the --ignore option.

Really need this, now fixed this by adding grunt-shell and making the phpdocumentor command without grunt-phpdocumentor..

Can you add this please? The pull request #10 is except for some testing ready for it i think!
